Abstract (en)
[origin: EP1020748A1] The present invention provides an optical information processing apparatus, in which input/output signal of an electric circuit is converted into an optical signal by a light receiving/emitting element, so as to be transmitted through an optical waveguide, and alignment between the optical waveguide and the light receiving/emitting element is easy. The apparatus comprises a waveguide substrate 10 provided with the optical waveguide, and an electric circuit substrate 100 mounted on the waveguide substrate 10 such that the electric circuit substrate is opposed to the optical waveguide 14. Here, a photodetector 101 for receiving light propagated through the optical waveguide 14 is arranged in a portion under the optical waveguide 14, and an electric circuit of the electric circuit substrate 100 is connected to the photodetector 101. <IMAGE>
